a
Quantities were determined in the headspace of meat samples analyzed as described in Materials and Methods. The results are expressed as mean values for volatile metabolites from 3 “technical repeats” ± standard deviations. The volatile metabolites listed in this table were absent from sterile (control) samples. —, under the detection/quantification limit.
